Two-way sync
Changes in Klaviyo or Veeva CRM instantly reflect in both systems. No stale data, no manual imports.
Keep Klaviyo and Veeva CRM in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Klaviyo holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Tags, Profiles, Lists, Segments in Klaviyo to Approved Email Activity, Accounts (HCPs and HCOs), Calls, Medical Inquiries in Veeva CRM with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Veeva CRM, and CRM data flows the other way wherever Klaviyo can store and use it.
Enriched fields land directly on records in Veeva CRM, and refreshes keep them from going stale.
Charges, refunds, and subscription changes appear on the account in Veeva CRM, so revenue context lives with the relationship.
Owner, lifecycle stage, or account details from Veeva CRM sync into Klaviyo, so people working there have the context without switching tools.
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Klaviyo objects | Veeva CRM objects | |
|---|---|---|
| Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. | Sample Transactions Sample disbursement records tracked for regulatory compliance. | |
| Tags Organizational labels on campaigns, flows, and lists support reporting rollups. | Consent Records Channel-level communication consent for HCPs, synced to enforce opt-outs across systems. | |
| Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Key Messages and CLM Content Approved content presented during calls, referenced in activity data. | |
| Lists Static audience memberships sync in from CRMs and forms for targeting. | Territories and Alignments Rep-to-account assignments, often fed from a roster or alignment system. | |
| Segments Dynamic audiences are readable so other tools can mirror who qualifies. | Events Medical events and speaker programs managed through Veeva's events capabilities. | |
| Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. | Approved Email Activity Sent-email records from Veeva Approved Email, used in engagement reporting. |

Klaviyo: REST API compliant with the JSON:API specification. Authentication: OAuth 2.0 for apps or private API keys. Veeva CRM: Salesforce-platform APIs (REST, SOAP, Bulk) for classic Veeva CRM; Vault REST API for Vault CRM. Authentication: OAuth 2.0. Stacksync manages authentication, retries, and rate limits on both sides.
Klaviyo: Klaviyo's current APIs follow the JSON:API specification, so payloads use typed resource objects with relationships rather than flat JSON. Veeva CRM: Classic Veeva CRM is built on the Salesforce platform, so Veeva entities are Salesforce custom objects (suffixed _vod) reachable through standard Salesforce APIs. Stacksync's field mapping accounts for these differences between Klaviyo and Veeva CRM without custom code.
